So I know this machine exists, I saw it years ago on youtube from harbor freight but I just cant recall the name or find it.
Basically sometimes you want a star washer to go into a chamfuer hole, i.e. in HP equipment. I saw a jig a while back that looked like a buncha bowl shaped craters in a metal block, with holes iirc, so you put the washer in, then put a appropriate ball bearing on top, then bend it into a bowl shape some how (press or hammer).
It cost like $25. Does anyone know of the kit? or an alternative? I think it was made for making belveill type washers or something.
I thought to drill a chamfuer hole into a steel block and try it that way, but IIRC the geometry of this was rounded, rather then inverted cone.. I think that leads to better bends\
it had like 20 of those craters and bearings so you can do various sizes
